Application of Fuzzy PID for the Ventilation and Air Conditioning System of Subway Station
The ventilation and air conditioning system in the public area of subway station is a complex system possessing a problem by once setting parameters of PID which is difficult to ensure excellent control effect. Therefore this paper proposed an algorithm to adopt parameter tuning that could adjust the PID parameters on real time to ensure good quality of control system. It combined fuzzy logic control with conventional PID control algorithm, with the help of fuzzy tuning of PID parameters to change the control effect on-line. By simulation, fuzzy PID controller could get better in control effect, higher in control accuracy, stronger in robustness than before.
